An Onen performs Tebillah and eats his Passover-offering in the Evening, but [He may] not [partake] of [other] sacrifices. One who hears about his dead [for the first time] , and one who collects the bones [of his parents], perform Tebillah and eat sacred flesh. If a proselyte was converted on the Eve of Passover, Beth Shammai maintain: He performs Tebillah and eats his Passover-offering in the Evening; while Beth Hillel
rule: one who separates himself from [the state of] uncircumcision is like one who separated himself from a grave.

He who was unclean or in a journey afar off` and did not keep the first [Passover] must keep the second. If he unwittingly erred or was accidentally prevented and did not keep the first, he must keep the second. If so, why is an unclean person and one who was in `a journey afar off specified? [to teach] that these` are not liable to Kareth, whereas those are liable to Kareth.
